5. During the late 1940’s, English biophysicists discovered that DNA crystallized when water is removed. This fact suggested that the atoms in DNA must be arranged in a very orderly fashion, perhaps with many repetitions of a fairly simple pattern. [ Finding - ]
6. In 1952, Americans Martha Chase and Alfred Hershey knew that viruses can attack bacterial cells and inject them with virus genetic information. They grew viruses with radioactive phosphorus in the DNA molecules and radioactive sulphur in the protein molecules. After these viruses attacked the bacteria and injected their genetic information, only one radioactive molecule was found inside the bacteria! Watch the animation to find out what they discovered.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

the answer is 100% density i've answered this question before and done the quiz myself.
